Abstract

There are shoals, islands, reefs, aquaculture farms and fishing nets in shallow sea (water depth 0~10m) .With the affected by natural and human factors, it’s very difficult to carry out marine survey activities in these shallow sea areas. In order to solve the problem of rapid and efficient pipeline verification in a wide range of shallow sea areas, this paper analyzes the composition and principle of the UAV aeromagnetic survey system, and selects a shallow sea area and coastal zone with submarine pipelines in Guangdong as the test area, and uses the UFO-CS multi-rotor cesium optical pump aeromagnetic measurement system and the MAG-DN20-G4 rotor UAV aeromagnetic detection system to carry out submarine pipeline detection tests in the area between 10 and 30 meters above sea altitude. The magnetic anomalies of the target pipelines at different altitude were compared. The test of UAV aeromagnetic technology in the verification of submarine pipelines in a small area of Guangdong provides a reference for the subsequent verification of submarine pipelines in Guangdong Province and even the whole country, and accumulates experience for exploring efficient magnetic exploration methods for cables in shallow sea areas.
